A kind of plastic extrusion molding processing method and equipment

Abstract

The invention relates to a plastic extrusion molding processing method and device. The method utilizes the extrusion process of an injection molding machine; finished extrusion products are bar shaped plates that can be truncated to a plurality of honeycomb boards, wherein bent plates are located on both sides of a delivering direction; the extruded finished products enter from an inlet of a stock mould and are sent out from the outlet of the stock mould; and when the extrusion products are passing through, the cavity of the stock mould shaping is introduced into vacuum, and under the vacuum action, two surfaces of the extruded finished product are pressed against the side wall corresponding to the cavity of the stock mould. According to the device, the sending direction of the extruded finished products is provided with the tock mould. The tock mould comprises deployable upper die and lower die, and a convex surface and a concave surface matched with the two surfaces of the honeycomb plate are arranged on the upper die and the lower die; when the upper die and the lower die are buckled, the convex surface and concave surface bread enclose into a cavity for extruded finished product to pass through, and the two ends of the cavity are provided with an inlet and an outlet along the sending direction of the extruded finished products; and the upper die and the lower die are respectively connected with a vacuum system, and the convex surface and the concave surface are provided with a plurality of grooves communicated with the vacuum system.

Description

technical field [0001] The invention relates to an extrusion molding method and device, in particular to a plastic extrusion molding processing method and device for a honeycomb board. Background technique [0002] For the thin honeycomb board, it has the characteristics of large area, small thickness and light weight, but for the honeycomb board with a bent structure, it is difficult to form. Usually, the manual forming method is to first make the honeycomb with bee eyes (that is, the middle of the board) hole) of the flat plate structure, and then use the flat plate as the bottom plate to be bent and shaped by flame baking; in this way, in addition to the relatively low production efficiency, the bottom plate is easy to be burned when the flame is baked, and the holes on the original bottom plate are baked. The position will change after baking, so it often needs to be corrected, which will reduce the quality of the bottom plate and make the quality of the product unstable...

[0002] For the thin honeycomb board, it has the characteristics of large area, small thickness and light weight, but for the honeycomb board with a bent structure, it is difficult to form. Usually, the manual forming method is to first make the honeycomb with bee eyes (that is, the middle of the board) holes) of the flat plate structure, and then use the flat plate as the base plate to be bent and formed by flame baking; in this way, in addition to the relatively low production efficiency, the base plate is easy to be burned when the flame is baked, and the holes on the original base plate are baked. The position will change after baking, so it often needs to be corrected, which will reduce the quality of the bottom plate and make the quality of the product unstable

For the existing automatic forming methods of honeycomb panels, most of them are used for thicker honeycomb panels, such as "a honeycomb panel decorative hole processing technology and the manufactured honeycomb panel with through holes" (publication number: CN101769432A) The disclosed technology shown is not suitable for thin honeycomb panels with large area and small thickness
